I can see the use of doing this. When The SimpsonsMovie was released, there was all kinds of merchandising. 7-Eleven even renamed their Slurpees into Squishees to promote it (and carried many other Simpsons merchandise, including Homer-style donuts). I suspect if Futurama ever got similar treatment, we'd see Slurm all over the place (right alongside "Bachelor Chow").

Actually, why wait for a movie? I want some Slurm now. Give me some Slurm. I need the stuff, man. I must have Slurm!
